FlowSyn continuous flow reactor is making high temperature chemistry available in no time at all

06/2008

The preparation of pharmacologically important 2-amino-pyridines by direct nucleophilic displacement of unactivated 2-chloropyridine requires harsh conditions and is typically low yielding. This situation can be resolved by the use of metal catalysed cross-coupling conditions, but this necessitates more extensive purification to subsequently remove the metal catalyst. Alternatively, the direct uncatalysed preparation of 2–morpholinyl-pyridine, for example, may be straightforwardly achieved conversion under continuous throughput conditions by heating a mixture of morpholine and unactivated 2-chloropyridine to 250oC in NMP for only 20 min.
